iOS 5 beta 2 blocks Gevey SIM Unlock, brings photo album curation to iDevices

It's only been a few days since Apple released iOS 5 beta 2, but we've already received a bevy of tips from developers who've spent some quality time with the update and uncovered a few of its more salient features. Here are some highlights.

• It looks like Apple has blocked Applenberry's Gevey SIM software, which allowed users to unlock devices running iOS 4.3 or iOS 5 beta 1 without having to jailbreak. (Read)
• According to Dev Team member MuscleNerd, iOS 5 beta 2 can still be jailbroken using theRedSn0w 0.9.8b1 tethering tool, released earlier this month. (Read)
• The beta refresh also brings a few tweaks to iOS 5's notifications system. Traditional alerts and reminders now pop up on the lock screen in larger typeface, alongside their appropriate icon. If left unattended, the notifications will eventually be added to the Android-like banner menu, at the top of the lock screen. (Read)
• Users can now create and curate photo albums directly from their iDevices, though the feature isn't without its quirks. A tipster informs us that photos added to new albums remain in the original collection, as well. If you migrate an image from one album to another and delete the original, both pics will disappear.
• The next beta release might be issued over the air. When a tipster checked for updates on an iPad running beta 2, he received a "No updates were found" message, suggesting that users may be able to find future refreshes without syncing their devices with iTunes. (Screenshot after the break.)
